Physicists turn to TikTok for science communication Forward this email  View in your browser THE WEEK IN PHYSICS: 3–7 JANUARY Advertisement AR's "U" Series Amplifiers Offers the Widest Bandwidth AR's "U" Series, Class A amplifiers covers a bandwidth of 10 kHz – 1000 MHz and delivers up to 500 W of power, making it ideal for EMC & laboratory testing, medical/physics research, antenna & component testing, wireless charging, & more! Imagine the possibilities with amplifiers that are Built to Last. Learn more. Colliding star clusters Two loosely bound groups of stars in the Milky Way are passing through each other. Charles Day Physicists turn to TikTok for science communication The platform's short, fun videos have helped scientists find new nonscientist audiences around the world. Madison Brewer Stacked materials build up massive electrons A heterostructure exhibits unusual electronic behavior previously seen only in materials with rare-earth or actinide elements. Heather M. Hill FROM THE VAULT: November 2006 Quantum gravity faces reality String theory is only one of many approaches to quantizing general relativity. Increasingly, all those approaches will be judged by how well they accord with experimental data. Lee Smolin Webinar Live Webinar: Dust Devils on Earth and Mars Desert whirlwinds or dust devils can be destructive, and even lethal. On Mars, they are a prominent meteorological phenomenon, causing surface changes, allowing us to track winds, and sometimes cleaning the solar panels of rovers. New observations and analyses let us predict their effects. Register now. White House clarifies disclosure requirements for R&D funding The federal government seeks to protect against threats posed by researchers' connections to certain foreign governments without stoking discrimination and xenophobia. Mitch Ambrose Coronavirus drug developed with the help of a DOE synchrotron Mapping a SARS-CoV-2 protein led to the discovery of a compound to disable it. David Kramer Webinar Live Webinar: Structural color: from birds to materials The feathers of red birds contain red pigment, but the feathers of blue birds contain no blue pigment. The blue color is structural, arising from scattering and interference. This webinar will discuss the physics of structural color, applications to materials, and why red is a tricky color to make.
